The Natural Abstraction hypothesis says that:

Our physical world abstracts well: for most systems, the information relevant “far away” from the system (in various senses) is much lower-dimensional than the system itself. These low-dimensional summaries are exactly the high-level abstract objects/concepts typically used by humans.
These abstractions are “natural”: a wide variety of cognitive architectures will learn to use approximately the same high-level abstract objects/concepts to reason about the world.
